NON-REFILLABLE BOTTLEl Specification of Letters Patent.

T0 (all whom, it may concern:

Be it known that I, MICHAEL LoETUs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention is a valve construction for non-refillable bottles, the principal features being a hollow air-tight member consisting of a bulb with a stem and a flange supported by a valve-disk, and above the bulb is a glass weight which normally keeps the valve closed.

In the accompanying drawings, Figure 1 is a vertical section of a bottle having my device. Fig. 2 is a sectional detail of the valve. Fig. 3 is an enlarged cross-section on the line 3 3 of Fig. 1.

Referring to the drawings, 10 indicates the tbody of the bottle, and 11 is the neck thereof,

which is provided with an internal annular flange 11a, which forms the valve-seat.

12 is a permanent stopper which is inserted and cemented in a screw-threaded part-11b at the top of the bottle and is provided with an opening 12a for a cork.

13 is a valve-disk, which is preferably made of rubber or any other similar material and which seats upon the flange 11a.

14 is a hollow member consisting of a hol-.

low glass bulb 14a, having a hollow stem 141 extending through the valve-disk 13 and at its bottom flared or flanged, as at 14C, the bulb and 'stem being air-tight and all, including the flange, being integral.

15 is a wei ht or plunger for normally keeping the vave closed and to prevent refilling of the bottle through its top. This weight 15 is of glass and is square or rectangular in cross-section; but any multisided shape may be used. The top of the weight4 is provided with cross-grooves 15a, which l provide outlets and prevent the weight from closing the opening 12at at the top when the bottle is inverted or turned over for pouring out the liquid.

`When the bottle is turned over to pour out the liquid, the fluid strikes the fiange 14C on the hollow member 14, which raises or causes the valve to leave its seat, the plunger 15 at the same time sliding to the open end of the bottle. The fluid may then be poured out. Attempt to refill the bottle causes the valve to close against its seat by reason of the weight 15. Attempt to force liquid in with the bottle inverted will cause the hollow member to float and close the valve.

Directly under the weight 15 the neck of l the bottle has an inwardly and upwardly projecting rib 16,` which serves to prevent the insertion of a wire or the like under the valve to lift the same. Should such a wire be inserted down beside the weight, the end thereof will engage the rib, and thus prevent the wire from reaching the valve.

I claim-v 1. In a bottle, the combination of a valveseat formed in the neck thereof, a disk valve which closes against said seat, a float comprising a hollow bulb having a stem extending through the disk, and a weight in the neck above said float.

2. In a bottle, the combination with a valve-seat formed in the neck thereof, of a valve which closes against the seat, a weight above the valve, and an inwardly-projecting annular rib extending around the neck under the Weight.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MICHAEL LOFTUS.
